Thanks Lynn. I'm glad my article helped
Its why I wrote it afterall
As for how much to feed, yes, I've said until they're bellies are rounded looking. If this proves difficult to determine I will offer a few thoughts. I've found that when a frog is no longer hungry, they will lose interest in eating. Most often, they will retreat back into the plants. I've never had a frog eat a dangerous amount of food and I think they're good at regulating themselves. You can try feeding them as much as they will comfortably eat (meaning, let them dictate when they start to lose interest, but dont' push them to eat more) and feed them that way every other day.
My adult frogs will eat about (I'm estimating here)...10 full size, plump frozen bloodworms at each feeding. Smaller frogs require less.
One note is that if you just purchased a frog, particularly if it is still very small, only feed it a few worms for its first few meals. Giving a starved frog a huge meal immediately can cause some stomach problems (similar to the way you have to work up to a full meal with starved cats/dogs).
I'm glad the baster method works well for you Lisa. I still stick by the tweezers though
Of course, they're only good if you get the long ones...using tiny tweezers is no fun at all! The frogs will get very adept at whatever method you choose in due time, anyway.
2 frogs in a 2.5g is the maximum I would suggest. If you upgrade to a five gallon tank, though, 4-5 frogs would be okay provided there were no other fish (a 5g with smooth rocks, sand, and frogs, is a wonderful thing).
